C# 日志框架的添加

.NET中 记录日志的比较好的主要是Log4Net和Enterprise Library的Logging

复杂一点的还可以实现自动化Log日志 教程

---

首先是第二种方式

1.需要添加以下几个DLL  下载

• Microsoft.Practices.EnterpriseLibrary.Logging.dll
• Microsoft.Practices.ObjectBuilder2.dll
• Microsoft.Practices.EnterpriseLibrary.Common.dll

2.Web.config 的configuration节点中添加以下内容

  <configSections>
    <section name="loggingConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.LoggingSettings, Microsoft.Practices.EnterpriseLibrary.Logging, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
    <section name="dataConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings, Microsoft.Practices.EnterpriseLibrary.Data, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
  </configSections>

  <loggingConfiguration name="Logging Application Block" tracingEnabled="true" defaultCategory="General" logWarningsWhenNoCategoriesMatch="true">
    <listeners>
      <add fileName="LogService.log" footer="----------------------------------------" formatter="Text Formatter" rollFileExistsBehavior="Increment" rollInterval="Day" rollSizeKB="10240" timeStampPattern="yyy-MM-dd" listenerDataType="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.RollingFlatFileTraceListenerData, Microsoft.Practices.EnterpriseLibrary.Logging, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" traceOutputOptions="None" filter="All" type="Microsoft.Practices.EnterpriseLibrary.Logging.TraceListeners.RollingFlatFileTraceListener, Microsoft.Practices.EnterpriseLibrary.Logging, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" name="Rolling Flat File Trace Listener" />
    </listeners>
    <formatters>
      <add template="时间: {timestamp} 类型: {severity} 标题: {title} 内容: {message}" type="Microsoft.Practices.EnterpriseLibrary.Logging.Formatters.TextFormatter, Microsoft.Practices.EnterpriseLibrary.Logging, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" name="Text Formatter" />
    </formatters>
    <categorySources>
      <add switchValue="All" name="Debug" />
      <add switchValue="All" name="General">
        <listeners>
          <add name="Rolling Flat File Trace Listener" />
        </listeners>
      </add>
    </categorySources>
    <specialSources>
      <allEvents switchValue="All" name="All Events" />
      <notProcessed switchValue="All" name="Unprocessed Category" />
      <errors switchValue="All" name="Logging Errors &amp; Warnings" />
    </specialSources>
  </loggingConfiguration>

注意：configSections节点一定要在loggingConfiguration节点的上面

3.调用

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Diagnostics;
using System.Reflection;
using System.Configuration;
using Microsoft.Practices.EnterpriseLibrary.Logging;
using System.Collections;

public sealed class LogWriter
{
    public LogWriter()
    {
    }

    /// <summary>
    /// 输出错误日志
    /// </summary>
    /// <param name="exception"></param>
    public static void WriteError(Exception exception, string title)
    {
        LogEntry logEntity = new LogEntry();
        logEntity.Title = title;
        logEntity.TimeStamp = DateTime.Now;
        logEntity.Message = exception.ToString();
        logEntity.Severity = TraceEventType.Error;
        Logger.Write(logEntity);
    }
}
